The angle made by the Earth's magnetic field with its vertical components is `60^(@)C`, the angle of dip at the place is ______.

Options

A. `60^(@)`
B. `30^(@)`
C. `90^(@)`
D. `0^(@)`

Explanation

To find the angle of dip when given the angle made by the Earth's magnetic field with its vertical component, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- The angle of dip is defined as the angle made by the Earth's magnetic field with the horizontal component of the magnetic field.

2. **Identify Given Information**:
- We are given that the angle made by the Earth's magnetic field with its vertical component is \(60^\circ\).

3. **Calculate the Angle with the Horizontal**:
- The total angle between the vertical and horizontal components is \(90^\circ\).
- If the angle with the vertical is \(60^\circ\), we can find the angle with the horizontal by subtracting this angle from \(90^\circ\):
\[ \text{Angle with horizontal} = 90^\circ - 60^\circ = 30^\circ \]

4. **Conclusion**:
- Therefore, the angle of dip at the place is \(30^\circ\).

### Final Answer:
The angle of dip at the place is \(30^\circ\).
